Amazon A+ Content: what it is and how to measure it

There is a conversation that repeats in every Mexican seller group. Somebody hires a designer, spends a few weeks building a good-looking block of images and text for their Amazon detail page, publishes it, and three months later nobody can say whether it helped. The most common answer is “I think so, it looks more professional”. That sentence costs money: it is an investment with no measurement, repeated product after product.

A+ Content — formerly called Enhanced Brand Content — is the enriched block that sits below the bullets on an Amazon detail page: large images, formatted text, comparison tables between your own products, brand story. It is the only part of the page where you can explain something that does not fit in seventy-five characters of title or five bullet points.

The commercial promise is clear and the platform repeats it: richer content helps conversion. The problem is not the promise, it is the execution. Most A+ published in Mexico gets built once, never revisited, rejected twice for reasons nobody understood, and never measured against a before and an after.

This article covers the four questions that matter: what it actually is, what you need to have it, what will get rejected, and how to know whether it moved the needle. With one warning up front: A+ rules change often, and the only source that counts is the Seller Central help for your account and your category.

what A+ Content is and where it lives

Think of the detail page as three floors. The top floor is the buy block: title, main images, price, Buy Box, bullets. The middle floor is A+ Content. The bottom floor is reviews and questions.

The top floor is read by somebody already deciding. A+ is read by somebody who still has a doubt. That distinction should govern what you put there: A+ is not a brand brochure, it is where you answer objections.

Amazon builds it from modules — predefined blocks of image, text or a combination — that you arrange on the page. Standard A+ allows a limited number of modules per page, and there is also a Premium A+ tier with richer modules: video, image carousels, interactive hotspots over an image, and enhanced comparison tables.

Premium is not automatic. Amazon has tied access to having brand content published and to accumulating a number of approved standard A+ modules over the previous twelve months. The exact requirements have shifted more than once, so check them in your own account before budgeting for video production.

what you need in order to use it

There is one entry condition and no shortcut around it: being enrolled in Amazon Brand Registry. Amazon’s brand registry generally requires an active registered trademark — or one far enough along, depending on the case — and the seller account linked to it.

Everything else follows from that:

• Standard A+ Content is available at no cost to sellers inside Brand Registry.
• Brand Story, the cross-catalog brand module that appears across your pages, also requires Brand Registry.
• Premium A+ unlocks from a history of approved A+, as described above.

If you resell third-party product and do not own the brand, this door is not for you. That is not a budget limitation, it is an intellectual property one: Amazon reserves enriched content for whoever answers for the brand.

One point that confuses many sellers: having Brand Registry does not mean every page is yours forever. On a shared detail page, the enriched content is published by the brand owner, and if that is not you, your A+ simply will not appear no matter how carefully you built it.

what you can include and what gets rejected

This is where the weeks disappear. A+ goes through review before publishing, and the most frequent rejection reasons are surprisingly boring and fairly consistent.

What Amazon generally does not allow in A+:

• Price and promotional language. No “$399”, no “20% off”, no “sale”, no “free shipping”, no “buy now”. A+ is product content, not an ad with a price inside it.
• Shipping, warranty or delivery-time references framed as a commercial promise. Those conditions are administered by Amazon, not by your image block.
• Contact details outside Amazon. Phone, email, your own website, social handles or any route that takes the shopper off the platform.
• Competitor names and comparisons against other brands.
• Unsubstantiated claims. If you say something is “number one”, “clinically proven” or “100% natural”, you have to be able to back it, and in several categories it is simply restricted.
• Reviews, testimonials or customer quotes inside the content.
• Images that mimic Amazon interface elements — logos, headings, badges — or that could be mistaken for parts of the platform itself.
• Low-resolution images, or images carrying too much text. Text inside an image is reviewed like any other text, and so is alt text.

One technical detail that saves rejections: everything you write inside an image counts as text for review purposes, and so does each image’s alternative text. Burning the forbidden word into the JPG does not help.

The list above is the general shape, not the literal rule. Claim restrictions vary a lot by category — supplements, personal care, children’s items and electronics all have their own — and Amazon adjusts them. Before sending a set of images to production for fifty ASINs, read the A+ guidelines currently live in your Seller Central.

how to build A+ that answers objections

If A+ is where doubts get resolved, the way to write it is to ask what stops somebody who already got that far from buying. In practice it is almost always four things:

• “Does this work for me?” Compatibility, real dimensions, the use case it was designed for. One image with the product in context and a visible measurement solves more than a paragraph.
• “How do I use it?” Steps, installation, maintenance. A shopper who does not understand how it works does not buy, and if they do buy, they return it.
• “Which of your versions is mine?” This is where a comparison table across your own products is worth gold. If you sell three capacities of the same item, that table stops the buyer from choosing wrong.
• “Who are you?” Brand Story, kept short. Brand history does not sell on its own, but it lowers the friction of buying from a stranger.

Two formal criteria matter more than they seem. The first is that most traffic is mobile: a block designed on a twenty-seven-inch screen with twelve-point text becomes unreadable on a phone. The second is that A+ sits below the decision: if your block repeats what the bullets already say, it is doing nothing.

The third is operational: when A+ contradicts the listing — the image says “includes three pieces” and the attribute sheet says two — you generate returns. That inconsistency between what the content promises and what the catalog describes is one of the most expensive sources of avoidable returns.

how to measure whether it actually moved conversion

This is the part almost nobody does, and without it A+ is faith.

Amazon has its own tool for this: Manage Your Experiments, its A/B testing feature for content. It is available to professional sellers with a brand in Brand Registry, and it works on ASINs with enough traffic to produce a statistically meaningful result. Amazon has been widening what can be tested — A+ Content and Brand Story among other things — and the tool itself tells you whether your product is eligible when you try to create the experiment.

That is the clean route. It splits traffic between two versions at the same time, which removes the seasonality problem entirely. If your product qualifies, use it before any homemade method.

If it does not qualify — and plenty of Mexican catalogs with moderate rotation do not — you are left with a before-and-after comparison, which works if you do it carefully:

• Publish the A+ on a single day and write the date down. Without changing price, main image or ad budget that same week.
• Compare equivalent, clean periods. Two or four weeks before against two or four weeks after, with no Buen Fin, no Hot Sale, no stockout in the middle.
• Look at conversion, not absolute sales. If you raised the ad budget in the second period, you sold more because you bought more traffic, not because the A+ works.
• Check the return rate. A+ that explains well lowers returns. A+ that overpromises raises them. That effect takes weeks to show and almost nobody goes looking for it.
• Close on margin. It is the only figure that integrates everything above.

A note of statistical honesty: if your product sells five units a week, no method — neither Amazon’s nor the homemade one — will give you a reliable answer in a month. At low volume, the right decision is to publish decent A+, skip the video budget, and spend the energy on the SKUs where there is enough data to learn something.

how this reads in iqseller

Worth being direct: iqseller does not create or edit A+ Content. It does not design modules, it does not generate images and it does not write the text of your brand block. All of that lives in Seller Central and will keep living there.

What the panel adds are the two pieces missing around it.

The first is Catalog. The Parent → Model → SKU tree ties the real product to its listings on every channel. That matters for A+ for a practical reason: when you build a comparison table across your own versions, you need to know which versions genuinely exist, which are still active and where they are published. An A+ comparing against a variant you discontinued is a mistake you discover through a buyer complaint, not through internal review. In the same vein, the panel lets you see listings that drifted out of alignment across channels: the same product described differently on Amazon and on MercadoLibre.

The second is Profitability, where the experiment closes. After publishing a new A+, the panel gives you, per SKU, the units, the orders, the average ticket and the real net margin built from the COGS you loaded, the commissions from Amazon’s settlement and from MercadoLibre orders, FBA and Full fees, shipping, advertising and the VAT and withholding breakdown. With that you can compare the earlier period against the later one without relying on a feeling.

Inventory and Alerts supply the context that validates or invalidates the reading: if the SKU had no real available stock for part of the period, or if a price moved in the middle, the before and after is not comparable and it is better to know that before drawing conclusions.

what is worth remembering

• A+ Content requires Brand Registry. Without your own registered brand, there is no door in.
• Premium modules unlock from a history of approved A+; the requirements have shifted, so confirm them in your account.
• The most common rejections are price, promotional language, off-Amazon contact details, competitor comparisons and claims you cannot substantiate.
• Text inside images and alt text get reviewed exactly like normal text.
• Design for mobile and for answering objections, not for looking impressive.
• Measure with Manage Your Experiments if your ASIN qualifies; if not, run a clean, honest before and after.
• At low volume no method will give you certainty. Invest where the data is.
• And most importantly: read the guidelines currently live in Seller Central before you produce anything, because these rules change frequently and vary by category.
